Description

Technical Field

[0001] The present invention belongs to the technical field of cantilever scaffold construction, and more specifically, relates to a cantilever scaffold based on multi-directional fixation and a erection method thereof. Background Art

[0002] A cantilever scaffold is an indispensable construction platform in building construction. It is suspended on the periphery of a building and can provide a stable operating platform for construction workers, facilitating construction operations outside the building, thus greatly improving the convenience and safety of construction. The structural design of the cantilever scaffold enables it to adapt to the construction requirements of buildings with different heights and complex shapes, providing a flexible solution for building construction.

[0003] However, the existing cantilever scaffolds usually adopt a structural form combining a base and the scaffold during erection. By firmly fixing the base on the floor of the building and then installing the scaffold on the base, the scaffold is suspended outside the building. Although this design can meet the basic construction requirements to a certain extent, it only supports the entire scaffold through a single connection structure between the base and the floor, and there are many problems with this single support method in actual use.

[0004] Firstly, the stability and safety of this single connection structure are relatively poor. During building construction, the scaffold often bears large loads, including the weights of construction workers, construction materials, and construction equipment. Relying solely on the connection between the base and the floor, it is difficult to ensure the stability of the scaffold under high-load conditions. Once the load exceeds the design range, the scaffold may shake or even collapse, seriously affecting the safety of construction workers and the construction progress. Secondly, the load-bearing capacity of this single connection structure is limited. Since the weight of the scaffold and the construction load are mainly transmitted to the building floor through the base, the connection strength between the base and the floor directly determines the load-bearing capacity of the scaffold. If the base is not fixed firmly enough, or the bearing capacity of the floor is insufficient, the scaffold is likely to deform or be damaged, thus affecting the normal progress of construction. In addition, when the connection structure becomes loose, the existing cantilever scaffolds lack effective safety measures. During construction, due to frequent operations and the influence of the external environment, the connection bolts or other fixing devices between the base and the floor may gradually become loose. If this loosening situation cannot be detected and handled in a timely manner, the stability of the scaffold will be greatly reduced, and it may even cause construction workers to fall from the scaffold, resulting in serious safety accidents. Summary of the Invention

[0005] In view of the above deficiencies or improvement requirements of the prior art, the present invention provides a cantilever scaffold based on multi-directional fixation and a erection method. By fixedly installing the mounting seat mechanism on the floor of the building, the scaffold is fixedly installed on the mounting seat mechanism, and the scaffold support mechanism is fixedly installed on the side of the scaffold and fixedly connected to the inner wall of the building. The mounting seat mechanism is fixed to the building floor to provide a rigid support base for the scaffold, avoiding risks such as shaking and settlement caused by direct contact with the ground, enhancing the wind load resistance and anti-overturning ability. The scaffold is rigidly connected to the mounting seat mechanism to form a stable vertical force system, ensuring uniform load transfer to the building structure and reducing local stress concentration. The scaffold support mechanism is fixed to the side of the scaffold and connected to the inner wall of the building to form a triangular stable structure of "floor - scaffold - inner wall", improving the lateral displacement resistance and reducing the horizontal load on the scaffold.

[0006] To achieve the above object, according to one aspect of the present invention, a cantilever scaffold based on multi-directional fixation is provided, including a mounting seat mechanism, a scaffold, and a scaffold support mechanism. The mounting seat mechanism is disposed on the floor of the building, the scaffold is fixedly installed on the mounting seat mechanism, and the scaffold support mechanism is fixedly installed on the side of the scaffold and fixedly connected to the inner wall of the building; wherein,

The third rotating U-shaped member is rotatably connected to a second telescopic component through a shaft rod. The other end of the second telescopic component is rotatably connected to a fourth rotating U-shaped member through a connecting shaft. A clamping plate is fixedly installed on the other side of the fourth rotating U-shaped member. An anti-slip plate is fixedly installed inside the clamping plate. A plurality of through reinforcement holes are provided on the clamping plate and the anti-slip plate, and the clamping plate and the anti-slip plate are fixedly connected to the outer wall of the building through bolts passing through the reinforcement holes.

[0010] Further, two fixing cylinders are spaced at intervals near the inner end of the upper surface of each fixing seat, and the plurality of vertical rods are fixedly installed in the fixing cylinders.

[0011] Further, the fixing component includes a fixing bolt. The outer wall of the upper part of the fixing bolt is provided with an external thread, and a slot hole is provided in its lower part. A casting hole communicating with the slot hole is provided at the top of the fixing bolt. A locking nut matching the external thread at the upper part of the fixing bolt is provided.

[0012] By pouring concrete into the slot hole of the fixing bolt, the concrete will overflow through the slot hole and solidify on the ground, forming a solid support structure, which enhances the connection stability between the fixing bolt and the floor.

[0013] Further, the anti - detachment component includes a T - shaped straight rail. The T - shaped straight rail is fixedly installed on the outer side wall of the fixed seat. A first threaded hole is provided at the top of the T - shaped straight rail, and a sliding block is slidably connected to its outer wall. The sliding block can slide along the length direction of the T - shaped straight rail. The inner side of the sliding block is adapted to the outer side shape of the T - shaped straight rail. A first locking bolt matching the first threaded hole is provided at the top of the sliding block.

[0014] Further, a fixed pipe is fixedly installed on the outer side wall of the sliding block. An anti - detachment pipe is sleeved outside the fixed pipe. A protective backing plate is fixedly installed on the side wall of the anti - detachment pipe facing the wall. A plurality of second threaded holes are provided at the top of the fixed pipe. A third threaded hole is provided near the inner end of the anti - detachment pipe, and a locking screw rod matching the third threaded hole is provided in the third threaded hole.

The sleeves are fixedly installed on the side walls of the vertical bars, and the central axes of the four sleeves are on the same horizontal plane. Through holes are provided on the first cross - bars and the sleeves. The first cross - bars are fixedly installed in the sleeves by passing a second locking bolt through the through holes on the first cross - bars and the sleeves.

[0018] Further, a fourth locking bolt is provided on the outer side wall of the installation cylinder. The installation cylinder is sleeved on the outer wall of the vertical bar. By tightening the fourth locking bolt, it tightly abuts against the outer wall of the vertical bar, thereby fixedly connecting the installation cylinder and the vertical bar.

[0019] Further, the second telescopic assembly includes a rotating rod and a rotating tube. The rotating rod is nested inside the rotating tube, enabling relative sliding between the rotating rod and the rotating tube. A plurality of mounting screw holes are provided on the side wall of the rotating rod, and a threaded bolt is provided on the side wall of the rotating tube near the inner end. The external thread of the threaded bolt matches the internal thread of the mounting screw hole, and a screwing plate is fixedly installed at the end of the threaded bolt.

[0020] According to the second aspect of the present invention, there is provided a method for erecting a cantilever scaffold based on multi-directional fixation, which is implemented by applying the above-mentioned cantilever scaffold based on multi-directional fixation, and includes:

[0021] S100: Place the parallel fixing seats on the building ground, and pre-drill holes on the ground that match the fixing components. Use the fixing components to firmly fix the fixing seats on the ground. By pouring concrete into the slot holes of the fixing bolts, the concrete will overflow through the slot holes and solidify on the ground to form a solid support structure;

[0022] S200: By rotating the locking screw, release the fixing restriction on the anti-disengagement tube, pull the anti-disengagement tube to adjust its total length with the fixing tube, so that the anti-disengagement tube can be stuck on the inner wall of the building. Then, by rotating the first locking bolt, make the protective backing plate contact the wall to prevent the anti-disengagement assembly from damaging the wall;

[0023] S300: Adjust the angle of the diagonal bracing assembly so that the support base is parallel to and in close contact with the outer wall of the building. Then use expansion bolts to fix the support base on the outer wall of the building to provide additional support and stability for the scaffold;

[0024] S400: Fix the vertical rod inside the fixing cylinder. According to the specific construction requirements, fix a plurality of bracket assemblies at appropriate height positions of the vertical rod;

[0025] S500: Fix the scaffold support mechanism on the vertical rod. By adjusting the length of the second telescopic assembly, ensure that the anti-slip plate is parallel to and in close contact with the inner wall of the building, and fixedly connect the scaffold support mechanism to the inner wall of the building through bolts.

[0026] Generally speaking, compared with the prior art by the above technical solutions conceived by the present invention, the following beneficial effects can be achieved:

[0027] 1. The multi-directionally fixed cantilever scaffold of the present invention fixes the mounting seat mechanism on the floor of the building. The scaffold is fixedly installed on the mounting seat mechanism, and the scaffold support mechanism is fixedly installed on the side of the scaffold and fixedly connected to the inner wall of the building. The mounting seat mechanism is fixed to the building floor, providing a rigid support base for the scaffold, avoiding risks such as shaking and settlement caused by direct contact with the ground, enhancing the wind load resistance and anti-overturning ability. The scaffold is rigidly connected to the mounting seat mechanism to form a stable vertical force system, ensuring uniform load transfer to the building structure and reducing local stress concentration. The scaffold support mechanism is fixed to the side of the scaffold and connected to the inner wall of the building, forming a triangular stable structure of "floor - scaffold - inner wall", improving the lateral displacement resistance ability and reducing the horizontal load on the scaffold.

[0028] 2. The multi-directionally fixed cantilever scaffold of the present invention fixes two fixed seats by using fixing bolts in the holes on the ground, adapts to different building structures by adjusting the position of the sliding block on the T-shaped straight rail, and unscrews the locking screw to release the limit fixation of the anti-disengagement tube, which can effectively adjust the overall length of the anti-disengagement tube and the fixed tube, ensuring that the two anti-disengagement tubes can be firmly stuck on the inner wall of the building, providing a solid support for the cantilever scaffold, improving the safety during the construction process, being convenient for maintenance, and helping to ensure the long-term stability and safety of the scaffold.

[0029] 3. The multi-directionally fixed cantilever scaffold of the present invention adjusts the angle of the diagonal brace assembly to make the support seat parallel and in close contact with the building exterior wall, and then uses expansion bolts to fix the support seat on the building exterior wall. Through the triangular structure formed by the diagonal brace assembly, the fixed seat and the building exterior wall, the stability and load-bearing capacity of the scaffold are significantly enhanced, effectively resisting the influence of external forces such as wind force or construction vibration. At the same time, it better disperses and bears the load applied to the scaffold, maintaining the integrity and safety of the structure, reducing the possible accidental risks during the construction process, and providing a safer working environment for workers.

[0030] 4. The multi-directionally fixed cantilever scaffold of the present invention fixes the scaffold support mechanism on the vertical rod. By unscrewing the threaded pin bolt, the limit locking of the second telescopic assembly can be released, and then the telescopic rod is pulled to adjust its length, ensuring that the anti-slip plate is parallel and in close contact with the inner wall of the building. The scaffold support mechanism is fixedly connected to the inner wall of the building by bolts. The mutual cooperation of the clamping plate and the telescopic rod, together with the vertical rod and the wall, constitutes a solid triangular structure, improving the structural stability of the scaffold, effectively dispersing the load borne by the scaffold, reducing the risk of structural deformation, enhancing the load-bearing capacity of the scaffold, improving the safety of construction workers when working on the scaffold, and providing a more stable and safe working environment for them.

[0045] Embodiment 1

[0046] As Figures 1-8 shown, an overhanging scaffold based on multi-directional fixation provided by an embodiment of the present invention includes a mounting seat mechanism 1, a scaffold 2 and a scaffold support mechanism 3. The mounting seat mechanism 1 is provided on the floor of a building. The scaffold 2 is fixedly installed on the mounting seat mechanism 1. The scaffold support mechanism 3 is fixedly installed on the side of the scaffold 2 and fixedly connected to the inner wall of the building. The mounting seat mechanism 1 is fixed to the building floor, providing a rigid support base for the scaffold 2 to avoid risks such as shaking and settlement caused by direct contact with the ground, and enhancing the wind load resistance and anti-overturning ability; the scaffold 2 is rigidly connected to the mounting seat mechanism 1 to form a stable vertical force-bearing system, ensuring uniform load transfer to the building structure and reducing local stress concentration; the scaffold support mechanism 3 is fixed to the side of the scaffold 2 and connected to the inner wall of the building to form a "floor-scaffold-inner wall" triangular stable structure, improving the anti-lateral displacement ability and reducing the horizontal load on the scaffold 2. This installation method makes the installation and disassembly of the scaffold 2 more convenient. During installation, only the scaffold 2 needs to be fixed on the mounting seat mechanism 1 and the scaffold support mechanism 3 is connected to quickly complete the installation; during disassembly, after the fixed connection is released, the scaffold 2 can also be quickly removed. In addition, the stable connection between the scaffold 2 and the inner wall of the building reduces the interference to the operation of construction workers caused by the shaking of the scaffold 2 during the construction process and improves the construction efficiency.

[0047] As Figures 1-6As shown, the mounting seat mechanism 1 includes two parallel fixing seats 4. A first telescopic assembly 10 is fixedly installed between the inner ends of the two parallel fixing seats 4. The first telescopic assembly includes a guiding cylinder 1001 and a guiding plate 1002. The guiding cylinder 1001 is sleeved outside the guiding plate 1002, enabling relative sliding between the guiding cylinder 1001 and the guiding plate 1002, for adjusting the distance between the two parallel fixing seats 4, improving the flexibility and adaptability of the mounting seat mechanism, and enabling it to adapt to building structures of different widths and diverse construction requirements.

[0048] Further, two fixing cylinders 9 are spaced apart near the inner end of the upper surface of each fixing seat 4 for fixedly installing the scaffolding 2.

[0049] Further, a plurality of pin holes 5 are provided near the outer end of each fixing seat 4. The fixing seat 4 is fixedly installed on the floor of the building through a fixing component 6 passing through the pin holes 5. The fixing component 6 includes a fixing bolt 601. The outer wall of the upper part of the fixing bolt 601 is provided with an external thread, and its lower part is provided with a slot hole 603. A pouring hole 604 communicating with the slot hole is provided at the top of the fixing bolt 601. A locking nut 602 matching the external thread of the upper part of the fixing bolt 601 is provided on the external thread of the upper part of the fixing bolt 601; by pouring concrete into the slot hole 603 of the fixing bolt 601, the concrete will overflow through the slot hole 603 and solidify on the ground, forming a solid support structure, enhancing the connection stability between the fixing bolt 601 and the floor, and providing a more reliable fixing foundation for the mounting seat mechanism 1, making it not easily displaced or loosened under the influence of external forces. In addition, the addition of concrete also improves the load-bearing capacity of the fixing bolt 601, enabling it to bear greater loads, reducing the risk of safety accidents caused by insecure fixing, and providing a safer working environment for construction workers.

[0050] Further, the anti-disengagement component includes a T-shaped straight rail 701. The T-shaped straight rail is fixedly installed on the outer wall of the fixing seat 4. A first threaded hole 703 is provided at the top of the T-shaped straight rail 701, and a sliding block 702 is slidably connected to its outer wall. The sliding block 702 can slide along the length direction of the T-shaped straight rail 701. The inner side of the sliding block 702 is adapted to the outer side shape of the T-shaped straight rail 701. A first locking bolt 704 matching the first threaded hole 703 is provided at the top of the sliding block 702.

[0051] Further, a fixed pipe 705 is fixedly installed on the outer side wall of the sliding block 702. An anti - detachment pipe 706 is sleeved outside the fixed pipe 705. A plurality of second threaded holes 707 are provided at the top of the fixed pipe 705. A third threaded hole 708 is provided near the inner end of the anti - detachment pipe 706. A locking screw rod 709 that matches it is provided in the third threaded hole 708. The fixed pipe 705 and the anti - detachment pipe 706 are fixed by the locking screw rod 709. By rotating the locking bolt 704, construction workers can accurately move the sliding block 702 along the length direction of the T - shaped straight rail 701 to adjust the support position of the scaffolding to meet specific construction requirements. Subsequently, the operation of rotating the locking screw rod 709 can release the fixation of the anti - detachment pipe 706, enabling the total length of the anti - detachment pipe 706 and the fixed pipe 705 to be adjusted, ensuring that the two anti - detachment pipes 706 can closely adhere to and firmly clamp on the inner wall of the building, providing a stable and safe support point for the scaffolding, greatly improving the flexibility and adaptability of the scaffolding. Secondly, the precise adjustment ability ensures the close fit between the scaffolding and the inner wall of the building, thus improving the stability and safety of the support. In addition, the simplicity of the operation enables construction workers to quickly make adjustments without complex tools, effectively improving the construction efficiency.

[0052] Further, a protective backing plate 710 is fixedly installed on the side wall of the anti - detachment pipe 706 facing the wall. When the anti - detachment pipe 706 contacts the wall, the protective backing plate 710 can effectively prevent the two from directly contacting, thereby preventing possible damage to the wall.

[0053] Further, the diagonal bracing assembly 8 includes a first rotating U-shaped member 801. A first rotating U-shaped member 801 is fixedly installed near the outer end of the lower surface of each fixed seat 4. The first rotating U-shaped member 801 is rotatably connected to a support plate 803 through a fixed shaft 802. The other end of the support plate 803 is rotatably connected to a second rotating U-shaped member 805 through a mounting 804. A support seat 806 is fixedly installed on the other side of the second rotating U-shaped member 805, and a plurality of threaded holes are provided on the support seat 806. The support seat 806 is fixedly connected to the building exterior wall through expansion bolts 807. The support seat 806 is fixedly connected to the building exterior wall through expansion bolts 807, and the expansion bolts 807 can penetrate into the interior of the wall to provide strong tensile force and stability; the diagonal bracing assembly 8 is rotatably connected at multiple points such as the first rotating U-shaped member 801, the support plate 803, and the second rotating U-shaped member 805, enabling flexible adjustment of the support angle in multiple directions, so that the diagonal bracing assembly can be quickly adjusted according to the actual shape and installation position of the building exterior wall to ensure its perfect match with the building structure, while meeting the support requirements in different scenarios; through the triangular structure formed by the diagonal bracing assembly 8 in combination with the fixed seat 4 and the building exterior wall, the stability and load-bearing capacity of the scaffolding 2 are significantly enhanced, effectively resisting the influence of external forces such as wind force or construction vibration, while better dispersing and bearing the load applied to the scaffolding, maintaining the integrity and safety of the structure.

[0054] As Figure 1 and Figure 6 As shown, the scaffolding 2 includes vertical rods 11 fixedly connected to a fixed cylinder 9. A plurality of bracket assemblies 12 are vertically spaced outside the plurality of vertical rods 11. The bracket assembly 12 includes two parallel first crossbars 1202. A second crossbar 1204 is fixedly installed between the two first crossbars 1202 through a third locking bolt 1205. The two first crossbars 1202 and the two second crossbars 1204 enclose a square frame structure, significantly enhancing the overall stability of the scaffolding 2, enabling uniform distribution of the load, avoiding excessive local stress, and thus ensuring a more stable construction process. At the same time, the load-bearing capacity of the scaffolding is also improved, enabling it to meet the requirements for carrying materials and personnel during construction, enhancing the practicability and safety of the scaffolding. In addition, the bracket assembly 12 is connected through a second locking bolt 1203, making the assembly and disassembly of the scaffolding more convenient. After the construction is completed, it can be quickly disassembled and recycled, improving the construction efficiency and reducing the labor intensity. This structure also has strong adaptability. The vertical rods 11 and the bracket assemblies 12 can be flexibly adjusted according to the actual needs of the construction site. For example, the number of bracket assemblies 12 can be increased or decreased to meet the construction requirements at different heights, enhancing the versatility and application range of the scaffolding 2; the square frame structure provides a regularized planar working space for construction, facilitating the laying of scaffold boards, the installation of safety nets, or the fixation of construction equipment, improving the convenience and safety of the operation.

[0055] Further, each of the bracket assemblies 12 further includes two sleeves 1201 sleeved on the outer walls of two mutually parallel first cross bars 1202. The sleeves 1201 are fixedly installed on the side walls of the vertical bars 11, and the central axes of the four sleeves 1201 are on the same horizontal plane. Through holes are provided on the first cross bars 1202 and the sleeves 1201. The first cross bars 1202 are fixedly installed in the sleeves 1201 by passing second locking bolts 1203 through the through holes on the first cross bars 1202 and the sleeves 1201.

[0056] Further, as Figure 1 and Figure 8 shown, multiple groups of scaffolding support mechanisms 3 are vertically and spacedly arranged on the two outer vertical bars 11. Each scaffolding support mechanism 3 includes an installation cylinder 13, and a fourth locking bolt 14 is provided on the outer side wall thereof. The installation cylinder 13 is sleeved on the outer wall of the vertical bar 11. By tightening the fourth locking bolt 14, it tightly abuts against the outer wall of the vertical bar 11, so as to fixedly connect the installation cylinder 13 and the vertical bar 11, thereby realizing the fixed connection between the scaffolding support mechanism 3 and the vertical bar 11. The multiple groups of scaffolding support mechanisms 3 vertically and spacedly arranged on the two outer vertical bars 11, the installation cylinders 13 of which are fixedly connected to the vertical bars by sleeving on the outer walls of the vertical bars and tightening the fourth locking bolts 14, can provide lateral support to resist horizontal forces (such as wind force, construction impact force), avoid the inclination and shaking of the scaffolding, and at the same time disperse part of the load to the building structure, reducing the risk of local stress and deformation of the vertical bars; this installation method is simple to operate, does not require complex tools, and is fast and flexible in installation and disassembly, facilitating the turnover use of the scaffolding; the support mechanisms arranged vertically and spacedly can flexibly adjust the installation position according to the construction height, and the position can be finely adjusted by loosening the bolts during the installation process, enhancing the adaptability to different construction scenarios and building storeys.

[0057] Furthermore, a third rotating U-shaped member 15 is fixedly installed on another outer sidewall of the installation cylinder 13. The third rotating U-shaped member 15 is rotatably connected to a second telescopic assembly 17 through a shaft rod 16. The other end of the second telescopic assembly 17 is rotatably connected to a fourth rotating U-shaped member 19 through a connecting shaft 18. A clamping plate 20 is fixedly installed on the other side of the fourth rotating U-shaped member 19. An anti-slip plate 21 is fixedly installed inside the clamping plate 20. A plurality of through reinforcing holes 22 are provided on the clamping plate 20 and the anti-slip plate 21. The clamping plate 20 and the anti-slip plate 21 are fixedly connected to the building exterior wall by bolts passing through the reinforcing holes 22. The third rotating U-shaped member 15 on the outer sidewall of the installation cylinder 13 is rotatably connected to the second telescopic assembly 17 through the shaft rod 16, which can realize the angle fine adjustment and length expansion and contraction of the second telescopic assembly 17, enabling it to flexibly adapt to the distance and angle deviation of different building exterior walls and avoiding installation difficulties caused by structural size differences. The other end of the second telescopic assembly 17 is rotatably connected to the fourth rotating U-shaped member 19 through the connecting shaft 18, further enhancing the angle adaptability when the clamping plate 20 fits with the exterior wall. Even if the exterior wall surface is uneven or has concave and convex structures, the clamping plate 20 can be closely fitted through rotational adjustment to ensure the fixing reliability. The anti-slip plate 21 can increase the frictional resistance between the clamping plate 20 and the wall, ensuring that the device will not easily displace or slide during use. The anti-slip plate 21 can also disperse the pressure of the clamping plate 20 on the wall, preventing the clamping plate 20 from causing indentations on the wall, thereby further protecting the appearance and structural integrity of the wall while ensuring the stability of the device. The through reinforcing holes 22 of the two can be fixed by multiple bolts to evenly disperse the load to the exterior wall structure, improving the connection strength and anti-pulling ability. This structure through multiple designs of "rotational adjustment + telescopic adaptation + anti-slip fixation" not only simplifies the installation process in complex exterior wall scenarios but also significantly enhances the connection stability between the scaffolding and the building main body, reduces the safety risks caused by connection failure, and is convenient for disassembly and turnover, improving the construction efficiency.

[0058] Furthermore, the second telescopic assembly 17 includes a rotating rod 1701 and a rotating tube 1702, and the rotating rod 1701 is nested in the rotating tube 1702 so that the rotating rod 1701 and the rotating tube 1702 can slide relative to each other. A plurality of mounting screw holes 1703 are provided on the side wall of the rotating rod 1701, and a threaded pin 1704 is provided on the side wall near the inner end of the rotating tube 1702. The external thread of the threaded pin 1704 matches the internal thread of the mounting screw hole 1703. Through the cooperation between the threaded pin 1704 and the mounting screw hole 1703, the length of the telescopic assembly can be adjusted according to the distance from the outer wall; the telescopic assembly consists of a rotating rod 1701 and a rotating tube 1702 that are nested and can slide relative to each other, the side wall of the rotating rod is provided with a plurality of mounting screw holes 1703, and the inner end side wall of the rotating tube is provided with a threaded pin 1704 matching therewith. The length can be flexibly adjusted according to the distance from the exterior wall, adapting to different construction scenarios and construction errors, and improving versatility and applicability; the threaded connection method is stable and reliable, enhancing structural stability and facilitating disassembly and maintenance; at the same time, the structure is simple, easy to manufacture and install, reducing manufacturing costs and improving construction efficiency.

[0059] Furthermore, the rotating rod 1701 is rotatably connected to the third rotating U-shaped member 15 , and the rotating tube 1702 is rotatably connected to the fourth rotating U-shaped member 19 .

[0060] Furthermore, a screwing plate 1705 is fixedly installed at the end of the threaded pin 1704 for easily rotating the threaded pin 1704 to avoid slipping, effort and the risk of hand injury, thereby achieving rapid positioning and fixation of the telescopic component length and accurately controlling the tightening degree.
